Jira Software V7.1.2 - Permission needed to add or modify workflow?

In Jira 7.12, is there a way to grant Project Administrator permission to edit workflow instead of giving them Jira Admin right?

Ideally, we want to grant project administrator the biggest right to do anything (including adding/editing workflows) inside his/her project, but I can’t seem to figure a way to do it for now. Please advise!
